In September 2010, Apple released the 2nd generation Apple TV. The new device is significantly smaller than the 1st generation Apple TV (released in 2007) and is focused on streaming media rather than downloading and storing it.

To disassemble the 2nd generation Apple TV you'll need a screwdriver with Phillips #1 and Torx T6 bits and a thin metal blade or plastic spudger.

The 2nd generation Apple TV costs $99 (US). It lets you rent movies and TV shows from iTunes and stream them to your television. The device can also stream music and videos from your PC or Mac running iTunes. It supports Netflix streaming and can be controlled with either a remote control (included) or via an iPhone, iPad, or iPod touch--using Apple's free Remote app.

Unlike the 1st generation Apple TV, this device is focused exclusively on streaming media from either the Internet or from a local machine running iTunes. As such, it lacks an internal hard drive.

In the box, you'll find the Apple TV, Apple Remote, power cable, and documentation.

Besides not including a hard drive, Apple shrunk the 2nd generation Apple TV by doing away with the Component video and RCA audio outputs. The newer unit also has a Micro USB port instead of the standard USB port found on the earlier version.

To crack open the 2nd generation Apple TV, you'll first need to remove the case's rubberized base. I used several thin, metal spudgers to pop the base free from the shinny black case. The base is held in place with plastic tabs. It may take a few minutes, but you should be able to pop the tabs free without breaking them.

With the base removed, we get our first look inside the 2nd generation Apple TV. At this point, there's not much to see other than the power supply, a large black heat sink, and a pink thermal pad stuck to the heat sink. Unlike the 1st generation Apple TV, the newer model lacks a hard drive or cooling fan.

A black, metal plate covers most of the printed circuit board (PCB). This plate likely serves as a heat sink to draw heat away from the chips on the PCB. A large, pink thermal pad is stuck to the heat sink. I assume this pad and the others like it inside the Apple TV help transfer heat from the internal components to the outer shell.

You should be able you remove the thermal pad in one piece. Once it's removed, we can see the five Phillips #1 screws that hold the heat sink and PCB in place.

With the heat sink removed, we get our first good look at the 2nd generation Apple TV's PCB. As expected, a metal EMI shield covers most of the chips. We'll need to remove the PCB from the case and then remove the shields to see what really makes this Apple TV run.

With the thermal pads, and two large EMI shields removed from the top of the PCB, we can see several of the 2nd generation Apple TV's main chips. The small EMI shield that covers the wireless chips appeared to be soldered to the small circuit board on which the chips were mounted. As I don't to damage any of the internal components, I'm going to leave the shield in place.

Interestingly, there appears to be space on the PCB bellow the current NAND flash chip for a second one.

The 2nd generation Apple TV was one of the easier cracking open projects I've tackled recently. Its has relatively few internal components, and the case opens without special tools.
